Fulltext Severe Orbital Myiasis Caused by Chrysomya bezziana: A Case Report

Ng YS, Gan YK, Tupang L

Turk J Ophthalmol, 2021 Feb 25;51(1):62-65.

An 88-year-old woman was brought to the hospital immediately after her neighbours noticed that she was bleeding from her right eye. On examination, her right eye was phthisic with maggot infestation of her right orbit. Over a hundred live maggots were extracted using forceps. Computed tomography scan revealed the infestation was confined to the right orbit. The patient underwent exenteration of the right orbit under general anaesthesia. The species was identified by an entomologist as Chrysomya bezziana, which has aggressive larvae that eat living tissue. This case report demonstrates that orbital myiasis caused by C. bezziana poses a very real risk of intracranial invasion as they feed on living tissues. Adjacent tissue destruction can be very rapid and definitive treatment involves urgent removal of its larvae via surgical debridement. To our knowledge, we are reporting the first case of orbital myiasis from a patient in Malaysia. Therefore, our case report may be helpful in the management of similar case of orbital myiasis.
A rare case of methicillin resistant Staphylococcus aureus (MRSA) cerebral abscess secondary to conjunctivitis

This case report discusses the rare association of cerebral abscess related to conjunctivitis in an otherwise healthy child. A 6 year old boy presented with conjunctivitis was treated with topical antibiotics and resolved after a week. Conjunctival swab cultures grew MRSA. A month later he developed status epileptics and CT scans revealed a large cerebral abscess. He was treated with intravenous antibiotics which covered for MRSA, along with an incision and drainage for the cerebral abscess. Pus cultures grew MRSA. The patient recovered well with no disturbance in visual acuity or visual field. On post-operative follow ups, he had no other neurological deficit apart from a slight limp.
Fulltext Baerveldt glaucoma implant with Supramid© ripcord stent in neovascular glaucoma: a case series

Gan YK, Birapadian SM, Abdul Jalal MI, Din NM

Int J Ophthalmol, 2024;17(2):265-271.
PMID: 38371250 DOI: 10.18240/ijo.2024.02.06

AIM: To report the outcome of Baerveldt glaucoma implant (BGI) with Supramid© ripcord use in neovascular glaucoma (NVG).
METHODS: We retrospectively evaluated the surgical outcome of the BGI with Supramid© 3/0 ripcord stent in patients with NVG. No tube ligation or venting slits were performed. Supramid was removed after 3mo if the target intraocular pressure (IOP) was not achieved. Surgical success was defined as IOP≤21 mm Hg with (qualified success) or without IOP-lowering medications (complete success).
RESULTS: Twenty-six eyes from 24 patients were included in the study. The median duration of follow-up was 4 [interquartile range (IQR)=1-5]y, ranging from 0.5 to 5y. IOP decreased by a mean of 24.2 mm Hg (59.7%); from a mean of 40.5±12.6 mm Hg at baseline to 16.3±11.9 mm Hg, P≤0.001. The number of glaucoma medications reduced from a median of 5 (IQR=5-6) to 1 (IQR=0-2, P≤0.001) at the final follow-up. Overall success rates were 88.0% at 1y, 34.8% at 3y, 66.7% at 4y, and 50% at 5y. Hypertensive phase (HP) in the first 3mo occurred in 15/26 eyes (57.7%) with a mean IOP of 31.1 mm Hg.
CONCLUSION: BGI with Supramid© ripcord stent gives close to 90% of the overall survival rate at the final follow-up without significant early hypotony. However, early HP is still a challenge.
